IMPROVEMENT lN MACHINES FOR UPSETTING TIRES.

Specification forming part of Letters Patent N0. B5HA67, dated June 2, 1874; application filed March 31, 1874.

To all whom it may concern:

Be it known that I, WILLIAM BowDEN, of Hamburg, in the county of Erie and State of New York, have invented certain Improvements in Tire-Upsetters, of which the following is a specification:

The invention relates to a portable selfa-djusting tire-upsetter; and the invent-ion consists in the arrangement and operation of the parts, as hereinafter explained.

In the drawings, Figure l is a sectional side elevation; Fig. 2, a plan.

A represents the cast-iron bed or frame, with grooves a a, in-which slide the clamp tables 13 B, one at each end of the machine. (J is the central stationary bed on which the red-hot tire I) rests, the other adjacent parts of said tire being held by serrated clamps or jaws c 0, two working on each table B. The outside of said clamps c c are provided with cogs, which mesh into corresponding cogs in eccentrics D D, set on steel pins (1, said eccentrics moving on the table 13, as shown. The other ends of the clamps ,c c are provided with slots 172, through which a rod or shaft, 0, passes. The slots at allow the necessary play to the clamps. This rod 0 is set into the upright parts of an end piece, E, which swings forward and back on pivots or pins f f at the base of the machine, the lower part g of the end piece standing out at right angles to the upright part, as shown in Fig. 1. h is a long spring, the end resting on a rod, 2', in the outer part of the end piece g,

' (see Fig. 1,) the object of this to be presently explained.

The construction of the tables B, clamps c c, eccentrics 1) D, end piece E g, &c., is precisely the same at both ends of the machine. Through the center of the frame A, at right angles, runs an operating-shaft, F, having double eccentrics F F just under the stationary bed-piece 0. (See Fig. 2.) 'Around these eccentrics work eccentric rods 7; is, their ends connected to the sliding tables 13 B.

A lever or crank, l, is attached to the shaft F, to operate the whole as follows: The tireB is heated at its thinnest or weakest point, and that part set on the central bed-piece C, while the contiguous parts of the tire rest on the slanting movable tables 13 B, and between the serrated clamps c c, as shown in Fig. 1. The shaft F is then given an eighth or quarter turn by means of the lever-handle Z. This operates the eccentrics on saidshaft, the rods or links k k drawing the tables toward the center, and, as they move, at the same time giving a self-action to the cogged eccentrics l) D on top of said tables, which operate at once on the clamps c 0, making them bite the edges of the tire. When these have taken hold all they can, the two opposite end pieces E move forward on their pivots ff to a sufiicient distance, or as far as the tables B carry them, until released by the action of the lever t. This holds the tire firmly, and also forces it together, or upsetting it, as it is called. The springs h h give that necessary amount of resistance or pull-back to the clamps c c to make them hold, and also throws the end piece E back into place when the lever is released.

These machines will do any kind of upsettin as well as on tires, and can be adjusted to any size of tires, &c., from one quarter to, say, live inches wide. It does away with all. and any wedges, which are apt to break the machine.

1. The swinging end piece E g, pivoted at ff, the springs h h, and the serrated andcogged clamps or tire-holders c c, with slotted ends, working on rod 0 in said pieces, all combined to operate as and for the purpose specilied.

The sliding clamp-tables I B, operated by the double eccentric shaft F F and rods 7; It, and the cogged eccentrics D 1), moving on pins (1 (I, and working in connection with the tire-holders c c, by means of the corresponding cogs, all combined as herein shown, for the object specified.

3. The frame A, bed piece C, sliding table B B, with eccentrics I) l), the swinging end pieces E 9, spring 7:, tireholders c c, and double eccentric shaft F F, and links 7c It, all combined and constructed to operate as hereinbefore set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
